Ran my finish pass at 800 SFM on 6061 for 2 months before a guy in Toledo asked what my spindle load was doing
Turns out I was cooking my inserts and blaming the tool holder, and when I dropped it to 500 the load graph went flat and my tool life went from 4 hours to a full shift, so what SFM are you all actually running on aluminum?

Ha, 800 was fine, you just messed up the coolant.
